History, Use, Propagation, Culture, 
to run down to the ground, and after they are concreted they are collected for use. These incisions are made 
at the beginning of August, when the weather is very dry, and are continued till the end of September. 
Turpentine and mastick are considered as astringent and diuretic ; but though they retain a place in our 
Materia Medica, they are not much used by modern practitioners. Mastick is used by the Turkish and 
Armenian women as a masticatory for cleaning the teeth and giving an agreeable smell to the breath. It is 
also employed to fill the cavities of carious teeth. {Thorn. Land. Disp. 444.) 
2066. Xanthoxylum. From |xv3-i9?, yellow, and ^vXov, wood. X. Clava- Herculis is esteemed a good timber 
tree in Jamaica; and an infusion of the leaves is used to cure the tooth-ach there and in Carolina. All the 
species may be increased by ripened cuttings, or by cuttings of the roots. 
2067. Picramnia. From ^rix^oi, bitter. A small tree with fruit the size of a gooseberry, and pinnate leaves ; 
the whole plant abounding in the bitter principle. Large cuttings strike freely in sand under a hand-glass. 
2068. Antidesma So called from the use of the bark in making ropes j from ocvri, like, and hio-fji-o?, a bond. 
A. alexiteria is a middle-sized evergreen tree, with leaves resembling those of the lemon, and fruit in racemes, 
red and acid like the barberry. A decoction of the leaves is reputed to be an antidote against the bite of 
serpents, and the bark is used for making ropes. All the species require a rich loamy soil, and ripened cuttings 
with their leaves on root in sand in a moist heat. 
2069. Iresine. Suppliants were accustomed among the Greeks to present themselves before the altar with a 
branch of olive bound with wool, which offering they called e<^S(r;9v»j ; whence this plant, which is very like 
such a branch, on account of its close clusters of woolly flowers, has been named. Herbaceous plants not of 
great beauty. 
2070. Spinacia. From spina, a prickle, on account of the processes of the seed. A well known annual 
esculent of the easiest culture in any rich soil. 
2071. Fluggea. Named by Willdenow, in honor of — — Fliigge, a German Cryptogamic botanist. A 
shrub with round ash-colored spiny branches. The spines are from one and a half to three inches long, very 
strong and numerous, whitish, and covered with leaves. 
2072. Acnida. From «, privative, and xvt^vi, a Greek name of the nettle; that is to say, a nettle-like plant, 
which does not sting. 
2073. Cannabis. According to Bullet, this name is taken from the Celtic can, a reed, and ab, small. But 
Golius says, the plant has been known by the Arabs from time immemorial under the name of qaneb. The 
hemp is a manufactorial plant of equal ant iquity with the flax. It grows to a great height on rich soils under 
a warm climate ; in some parts of Italy it has been found eighteen feet high (Cruds. Agr.) ; the common 
height in Lombardy and the Bolognese territory is twelve feet; in this country it seldom exceeds six feet, and 
the fibre of British hemp is no finer than where it is three times the length. The culture, management, and 
uses of hem,p are nearly the same as those of flax ; but the male and female flowers being on different plants, 
and the male plant decaying long before the female, the former requires to be pulled up as soon as the setting 
of the seed in the females shews that they have effected their purpose. Hemp is sown on well prepared
